Problems solved by technology
The production methods of nano-titanium dioxide used in the above products generally include sulfuric acid method and chlorination method. The titanium dioxide prepared by these methods has the following disadvantages, such as complex process, high cost, serious pollution, and low catalytic efficiency; in addition, most of the nano-titanium dioxide products sold in the market It is a single-phase titanium dioxide. This titanium dioxide has a certain decomposition effect on harmful gases, but the effect is poor. It has been proved by experiments that the metal hybrid nano-titanium dioxide has a more obvious purification effect on harmful gases than the former, and has a good catalytic effect. Decomposition
